cation.

This invention relates to apparatus for obtaining a supply of air orgas, carbureted and containing hydrocarbons, for illuminating purposesand at the same time to supply hydrocarbon fuel to'a carburetor of anen- The invention consists incarbureting' apparatus for air or gascomprising a fuel reservoir from which fuel passes to a chamber in whichthe air or gas is carbureted and from which a passage leads to theengine carbureter so that the fuel is led away from the carburetingchamber to the engine carbureter, its place being taken by a freshsupply whereby the composition of the fuel in the carbureting chamber iskept substantially constant.

The invention further consists in the improved apparatus hereinafterdescribed.-

The accompanying drawing illustrates diagrammatically one form of thepresent invention, the chamber a, and the reservoir n, being shortenedfor the purposes of illustration.

lln carrying the invention into eect according to one form there isprovided a reservoir (1., preferably of cylindrical form having two ends6 and c which are flat or very slightly convex. The lower end 6,supports at its center a rigid rod d, screwed into a Y fitting e, fixedin a fluid tight manner to the end 7). The lower end of the rod 0? has anotch f to allow of the introduction of a screw driver therein, for thepurpose of adjusting the rod in the fitting e. A cap 9' serves toprotect the end of the rod and to insure a fluid tight joint. The otherend of the rod d carries a valve head k, the seat 1: of which is fixedin a fluid tight manner to the cover 0 of the chamber. This valve iscovered by a cap k which serves to admit the air or gas to be washed andcarbureted. The seat of the valve 2' extends downward in the form of atube Z which is fixed to the cover a and is guided at its lower end bythe fitting e on which it can slide freely. At a short distance from thebottom of the chamher, the tube is perforated with holes m distributeduniformly around the tube.

Ata certain distance from the upper end of the reservoir there isarranged abafie constituted by two-plates t t fixed, one to the wall ofthe chamber, and the other'to the tube 1. At 0 there is a safety valvefor preventing too great arise of pressure in the interiorof thechamber. It is assumed that the chamber a is filled to a certain levelbe-- low the plates t with the carbureting. liquid.

The operation of the apparatus is as follows-:The air or gas to becarbureted is supplied by a pump or other suitable means (not shown)through the cap 7;. at a certain pressure. It passes through the spacebetween the head h and the seat 2" and thence takes its course betweenthe rod 0'. and the tube Z to the level of the holes m. 0n issuing fromthese holes it bubbles up through the liquid and reaches the upper partof the chamber, whence it passes away through the it is desired tomaintain to the top of the tank a as shown. The pressure in the chambera is above atmosphere by an amount equivalent to the difiere'nce inlevels of the liquid in the chambers m and a. If the pressure risessulficiently to force the level in the chamber down to the point atwhich the pipe enters that chamber, there is an immediate'flow of fuelfrom the chamber m so that the level is maintain in chamber a at thelevel of thepipe p as shown in the drawing. The operation of the chambera in order to maintain a constant pressure in that chamber is asfollows:

Assuming that for some reason the pressure inside the chamber (1increases then the two ends b and 0 will undergo a proportionate elasticdeformation and the two fit- I tings z and'e will have a tendency tomove conduit 9 and cock at. The conduit 9 is led is connected to themain, fuel reservoir n and c apart sufliciently to close the valve 2'completely. Therefore, if the pressure .of

the air or gas to be carbureted is always ".greater than that limit, theinternal pressure will remain constant and will approxi:

- mate the more closely to this limit'the greater the surface of thevalve, because then on the least drop of pressure-in the reservoir belowthis limit the valve will open and allow a further quantity of air orgas 'to pass into the chamber a, which quantity will tend to bring backthe pressure to what it 'was previously.

This apparatus being intended for use on motor cars, it is provided atits lower part with two connectors i and 8, the connector 8 feeding'theenginewhile other connector 1' is adapted to be connected to thecarbureter 'of the engine. The connector 9 can be connected at will bythe cocku tothe lamps for lighting. -Under these conditions let it beassumed that through is there is admitted compressed mixture air, orexhaust gases from the engine cylinder, or any other gas supplied by theengine or from an independent s'ource. The level of the liquid will sinkto the level of the connector 1), irrespec- .tively of the level in themain reservoir n of the motor provided that the latter is fluidto thedepth between the holes m, and the level of the liquid so that the gasis regularly 'carbureted and washed by bubbling up through a liquidcolumn of constant height and concentration which 1s contmually beingrenewed.

- Having'now described my invention, what I'claim as new 'and desi're'to secure by Let ters Patent is 4 I Means for supplying both combustiblegasand liquid fuel comprising in combina' tion a fuel supply tank, acarbureting chamher, said carbureting chamber having flexible ends, avalve stem connected to one end.

of said chamber, a valve box secured to the other end of said chamber, avalve seat formed in said valve box, a gas supply pipe leading into saidvalve box, two pipes conmeeting said fuel supply tank with saidcarbureting chamber, one-of said pipes leading from the bottom of saidtank tothe bottom of 'saidchamber, the other of said pipes leading fromthe top of'said tank-to an intermediate point in the height of saidchamber, a guiding tube fixed to the top of said carbureting chamber,said tube having-perforations below the level of the 'li uid in saidcarbureting chamber, as and or the purpose set forth.

In testimony whereof I have signed my name to this specification in thepresence of two' subscribing witnesses.
